I use a campbel hausefield airless sprayer. $300 It works great. I upgraded to a grayco sprayer$100 and added 50 ft more of hose. I can afford a better sprayer but this works so well, why change? They last about 4-5 years for me and they can be restored when the piston stops building pressure. Simply remove the head off the pump and add power steering fluid to the resivoir and tighten head back down. This is necessary every 3yrs or so. I have had GREAT luck with these machines .
